3.0 PHYSICAL PROPERTIES

Colour: Milky White.
Weight per gallon: 9.4 lbs. Curing conditions: 70 F & 50% relative humidity.
Estimated cure time: 24 hours.
Minimum ambient, surface & product installation temperature: 60 and rising.
Note: Low temperatures or high humidity will increase drying time drastically. Maximum surface temperature = 140 F.

4.0 SURFACE PREPARATION

4.1 BASE CONSTRUCTION

Surface must meet or exceed the American Sport Builders Association (ASBA) applicable Guidelines. Upgrading and recoating previously colored surfaces requires the surface and base construction to be in sound condition and in compliance with the applicable ASBA Guidelines.

4.2 ASPHALT CURING REQUIREMENTS

New hot-mix asphalt surfaces must allowed 14 days minimum curing time prior to the application of the Deco products. For new concrete surfaces, a minimum of 28 days curing time is required.

4.3 SURFACE CONDITION

The surface on which Acrylic Patch Binder is to be applied must be smooth, free of dirt, loose or flaking paint, oily materials or chemical residues, vegetation of any sort and any other debris or foreign matter that may prevent the proper product adhesion.

4.4 SURFACE IMPERFECTION

Prior to the application of surfacing materials, the entire surface shall be flooded with water and allowed to drain. Any depressions capable of submerging a U.S. five-cent piece after one hour should be marked with chalk, not crayon or a grease pencil. These areas must then be allowed to thoroughly dry. Once dried, a patch must be applied to the marked areas.

5.0 MIXING INSTRUCTIONS

The following mix has been found to be satisfactory for average surface conditions: Dry Silica Sand (60 - 80 Mesh) 100 lb Portland Cement (Type 1) 1-2 gallons. Portland Cement (Type 1) 1-2 gallons. Acrylic Patch Binder 920-39 3 gallons.

DO NOT ADD WATER!

In a clean container, thoroughly premix the sand and Portland cement. Add Acrylic Patch Binder into mixture.A mechanical drill mixer is recommended and mixture should be stirred until homogeneous. Periodic mixing should take place as job progresses to ensure consistent application. Batches shall be used within 15 minutes.

6.0 GUIDE TO APPLICATION

6.1 SYSTEM RECOMMENDATION

Acrylic Patch Binder is intended for patching voids and depressions from 1/8" to 1 1/2" deep. Do not install Acrylic Patch Binder mix in lifts greater than 3/4" inch. Deco recommends the use of Acrylic Resurfacer 920-29 after the application of Acrylic Patch Binder. See the data sheet 920-29 for Acrylic Resurfacer.

6.2 INSTALLATION

Acrylic Patch Binder is best installed with a trowel or straight edge. The area to be patched should first be primed with a diluted coat of Acrylic Patch Binder . Do not dilute more than 2 parts water to 1 part Acrylic Patch Binder. The area should be brushed, broomed or rolled over the entire area, and allowed to dry at least 1 hour.

6.3 DRYING AND CURE TIME

Acrylic Patch Binder must be allowed to dry before applying next coating application. When applying multiple coats of Acrylic Patch Binder a minimum of 24 hours of cure time is required between coats, and not before first application is fully dried.

7.0 COVERAGE

Based on size, depth and texture of area to be patched.

8.0 CLEAN-UP

All equipment can be cleaned with water if clean-up occurs immediately after application. Rinse water should be reserved for later use.

9.0 LIMITATIONS

Based on size, depth and texture of area to be patched.

9.1 SURFACE LIMITATIONS

Acrylic Patch Binder is limited to application on hot-mix asphalt and Portland cement concrete recreational surfaces. Deco Surfacing Systems does not recommend, nor authorize the application of Acrylic Patch Binder on any other surfaces without prior approval from your Deco Area Manager.

9.2 WEATHER LIMITATIONS

No part of the construction involving the Deco Surfacing System should be conducted during rainfall, or when rainfall is imminent. The air temperature must be at least 60ºF and rising. Do not apply when surface temperature is above 140ºF.

9.3 DO NOT OVER DILUTE

Do not dilute primer coat more than 2:1. Over dilution will cause adhesion failure, and poor overall durability of the coating. Only the primer coat is diluted, not the Acrylic Patch Binder.

9.4 DO NOT APPLY THICKER THAN 3/4" PER APPLICATION

If leveling depressions greater than 3/4", apply Acrylic Patch Binder in multiple lifts. Each lift must be allowed to dry between applications. Do not use for voids more than 1-1/2" deep.

9.5 INDOOR APPLICATION CURING

Drying times are retarded by high humidity, cool temperatures or lack of air movement. This is particularly important to note when installing indoors, where all three factors are often very pronounced.

9.6 KEEP FROM FREEZING

Acrylic Patch Binder is a water-based acrylic and it must be kept from freezing during storage or in transit. If you receive product you suspect may have been exposed to freezing temperatures, consult your Deco Area Manager for proper handling instructions.
